Æther Model – Effective Renormalization Group Dynamics in the Dynamic Vacuum

This technical monograph (in Spanish) presents a systematic analysis of the effective renormalization group dynamics within the dynamic vacuum regime of the Æther model. The study is explicitly restricted to a finite effective domain characterized by non-vanishing physical differentiation of the vacuum, and does not address ultraviolet completion or foundational formulations of the model. An internal, operational notion of scale is introduced, tied to the dynamical state of the vacuum itself, and the resulting effective flow equations are analyzed. The work establishes the structural absence of strict renormalization group fixed points within this domain and identifies quasi-fixed regimes, dynamical attractors, and forms of internal universality without exact scale invariance. The analysis is fully self-contained, structural in nature, and intended as an internal development within the broader Æther research program.
